Patents by Inventor Austin V. Harton

Austin V. Harton has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Optical isolator having leadframe with non-planar mounting portions
    Patent number: 5751009
    Abstract: An optical isolator (10) includes an opto-electronic emitter (16) and an opto-electronic detector (17) mounted over offset portions (12, 13) of a leadframe (11). The offset portions (12, 13) form angles (14, 15) with other portions (24, 25) of the leadframe (11). An optically transmissive material (22) encapsulates the opto-electronic emitter (16) and the opto-electronic detector (17), and a reflective material (20) is located above the opto-electronic emitter (16) and the opto-electronic detector (17). An optically insulative packaging material (26) encapsulates the optically transmissive material (22).

  • Holographic optical isolator utilizing opto-electronic transmitter and receiver disposed in a package
    Patent number: 5500912
    Abstract: An opto-isolator (10) increases optical efficiency by using holographic elements (22,24,26) to direct a beam of light (34) through an optical waveguide (20). An opto-electronic transmitter (12) and receiver (16) are connected to the waveguide to be in alignment with the beam of light reflected by the holographic elements. The transmitter and receiver are disposed on separate leadframe portions (14,18), and the opto-isolator is surrounded by a package (32).
